Abstract

Investigating the use of prismatic lenses with cross-sectional shapes inspired by the apposition compound eyes of some dipterans, we found through numerical simulations that the exposed surfaces of silicon solar cells should be textured as arrays of bioinspired compound lenses (BCLs) in order to improve performance. We used a ray-tracing algorithm to evaluate the light-coupling efficiency over a large wavelength range of the solar spectrum. Thus, the array configuration maximizing the light-coupling was determined. Results show that the light-coupling efficiency can be enhanced by at least 16% with respect to that of a silicon cell with a flat surface.
